Serverless: Inheritence of Cloud Computing

Serverless computing is a cloud computing execution model in which the cloud provider dynamically manages the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity. It is a form of utility computing.

Serverless computing still requires servers. The name "serverless computing" is used because the server management and capacity planning decisions are completely hidden from the developer or operator. Serverless code can be used in conjunction with code deployed in traditional styles, such as microservices. (Microservices is a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services.) Alternatively, applications can be written to be purely serverless and use no provisioned services at all.

AWS Lambda, introduced by Amazon in 2014, was the first public cloud vendor with an abstract serverless computing offering. AWS Lambda initially supported only Node.js. It now supports Python, Java, and C#, and code written in other languages can be invoked indirectly via Node.js.

Serverless computing is more cost-effective than renting or purchasing a fixed quantity of servers, which generally involves significant periods of underutilization or idle time. It can even be more cost-efficient than provisioning an autoscaling group, due to more efficient bin-packing of the underlying machine resources.
